Yes, I don't know what the problem is, but it's happened with two different situations: first, I was downloading stuff in BitComet. BC could be running with no problems, but downloading stuff made problems, and it would kill my (usb) internet adapter (wireless). second, I had a labelmaker for my new lightscribe drive open (only thing I can think of) and it shut off. Same thing everytime too, it shuts off the usb port, for anything, I can plug in my usb headset to the port and it won't work. It's getting really annoying becuase simply changing the usb port doesn't help, I have to restart the computer to reset that usb controller.
